Let’s be honest: if you’re a front-end dev, your browser is basically your second home. You’re in there, debugging, designing, and optimizing your projects day in and day out.
But while Chrome and Firefox are great out of the box, adding a few extensions can turn them into full-blown development environments that make your workflow 10x smoother.
Here’s a roundup of the must-have browser extensions for front-end developers in 2024.
*1. React Developer Tools *
If you’re working with React (and let’s face it, who isn’t?), this extension is non-negotiable. It lets you inspect your React component hierarchy right inside the browser, so you can see state, props, and context as you debug.
Why it’s essential: No more console.log() debugging or sifting through messy DOM structures to find where your component is breaking.
*2. Web Developer *
Old but gold, the Web Developer extension adds a toolbar with various options to inspect and manipulate your page’s elements, including CSS, forms, and images.
Why it’s essential: It’s like the Swiss Army knife of browser extensions. You can disable CSS, resize the browser, validate HTML, and more—all in one place.
*3. Wappalyzer *
Ever land on a site and wonder, “What stack is this running on?” Wappalyzer instantly reveals the technologies behind a website—frameworks, CMS, eCommerce platforms, analytics tools—you name it.
Why it’s essential: Perfect for those moments when you want to borrow (steal) a few ideas or simply understand what tools other developers are using behind the scenes.

*4. ColorZilla *
When you see a color you like, and you want it now, ColorZilla is your go-to. It’s an eyedropper tool that lets you grab colors from any website and copy them in different formats like HEX, RGB, or HSL.
Why it’s essential: It saves time by eliminating the need to dig through CSS or use design software just to find that perfect shade of blue.

*5. WhatFont *
Fonts are as important as colors, and sometimes you need to know exactly which one is being used without diving into the dev tools. WhatFont lets you hover over any text and immediately get details about the font family, size, weight, and style.
Why it’s essential: Font identification made easy. Great for when you’re looking for inspiration or matching typography across projects.
*6. Lighthouse *
Google’s Lighthouse tool is integrated directly into Chrome, but having the extension makes running audits a breeze. It gives you a detailed performance analysis of your web page, scoring your site on speed, SEO, accessibility, and best practices.
Why it’s essential: With 2024 shaping up to be a year where performance is non-negotiable, Lighthouse helps ensure your site is not just fast but also SEO-friendly and accessible.

*7. Grammarly *
While this isn’t a dev tool in the strictest sense, Grammarly is invaluable for front-end devs who are writing documentation, creating user-facing content, or commenting on their code. It catches typos, and grammar mistakes, and even suggests clearer ways to express ideas.
Why it’s essential: Communication is key, and whether you’re writing docs or copy for your UI, Grammarly ensures everything is polished.

*8. Tab Modifier *
This extension allows you to rename and pin tabs, ensuring that you don’t get lost when working with multiple browser tabs. It’s highly customizable, so you can color-code, auto-close tabs, and more.
Why it’s essential: If your dev workflow looks like 50 open tabs, Tab Modifier helps you stay organized and saves you from accidentally closing an important tab in the middle of a task.

*9. PerfectPixel *
When pixel-perfect design is non-negotiable, PerfectPixel helps you overlay a semi-transparent image of your design mockup on top of the web page. This lets you compare and align everything down to the last pixel.
Why it’s essential: Ensures that what you design in Figma (or Sketch, or whatever) looks exactly the same in the browser. No more arguing with designers about 1px margin differences.
*10. Page Ruler Redux *
This tool gives you an on-page ruler so you can measure elements directly within the browser. Need to check the spacing between two components or measure a div’s height? This extension’s got you covered.
Why it’s essential: Saves you from the trial and error of resizing elements in CSS. It’s a must for aligning and fine-tuning designs.
